The objective of this study is to determine the long term safety and tolerability of multiple oral doses of tipranavir (Aptivus) and ritonavir with a focus on the long term safety of the development dose (500 mg tipranavir/200 mg ritonavir BID) when administered with other antiretroviral medications.

Ability and willingness to give written informed consent in accordance with institutional and federal guidelines and to comply with the investigational nature of the study and the related requirements.

All subjects must have successfully completed participation in a combination tipranavir/ritonavir trial or have confirmed virologic failure in the 1182.12 or 1182.48 trials and are not able to obtain TPV by prescription. Successful completion of participation is defined as conclusion of required subject-weeks on assigned dosing (trial specific) and completion of required visits.

Male and female subjects 18 years and over.

Presence of Human Immunodeficiency Virus 1 (HIV-1) infection as documented by any licensed Enzyme Linked immunosorbent Assay (ELISA) test kit and confirmed by Western Blot, or HIV-1 culture, or HIV-1 antigen, or plasma HIV 1 Ribonucleic Acid (RNA) or a second antibody test by a method other than ELISA at any time prior to study entry.

Are not willing to use a reliable method of barrier contraception (such as diaphragm or condoms).

Are breast-feeding.

Subjects who are actively using injection drugs or other substance abuse (such as extensive alcohol or narcotic use) which is considered by the investigator to be a significant impairment to health and to protocol adherence.

Any medical condition(s) which, in the opinion of the investigator, would interfere with the subject's ability to participate in or adhere to the requirements of this protocol.

History of any illness or drug allergy which, in the opinion of the investigator, might confound the results of the study or pose additional risk in administering tipranavir/ritonavir to the subject.

Active use of any of the following:

Investigational HIV-1 vaccines.

Any new investigational antiretroviral agent that was not approved for use in the patients prior tipranavir trial.

Medications excluded during the trial period (see Section 4.2).

Herbal medications (e.g., St. John's Wort).

Active HIV-related or non HIV-related illness that may be negatively affected by use of tipranavir/ritonavir as determined by the investigator.

If a subject must temporarily discontinue tipranavir/ritonavir at the recommendation of the investigator (at the completion of the previous tipranavir trial), then the subject may enroll in 1182.17 once the clinical illness has resolved, and after approval from the Boehringer Ingelheim Clinical Monitor or Local Clinical Monitor.

Voluntary discontinuation of antiretroviral therapy (including tipranavir/ritonavir) for more than seven days from completion of previous tipranavir trial.
